Description
Technical field
The present invention relates to the food cooking appliance, the general technology field of domestic type utensil especially, this utensil is designed to form airtight boiling container, food in this container under the steam pressure effect by boiling.
The present invention relates more specifically to a kind of inner pressure-cooking appliance that lid is installed that has, and this pressure-cooking appliance comprises at least:
-bowl and lid, this lid is designed to be mounted in described bowl at least and can moves between closed position and open position, in described closed position, described lid cooperates with described bowl to form the boiling container of basic sealing, and, can make the inside and the external communications of described container at described open position; With
-control device, this control device is used to make described lid to move between its closed position and its open position, and be mounted at least and the corresponding primary importance in closed position of described lid and and the corresponding second place of open position of described lid between move.
Background technology
In the prior art, this utensil of the pressure-cooking appliance of pressure cooking-pot type, especially family expenses is well-known.
This utensil generally comprises bowl and lid, and cover design becomes to be installed on the bowl, forming the boiling container of closing with air tight manner, and treats that the food of boiling is placed in this container.Therefore, the inside of container can reach high pressure and high temperature when utensil is subjected to influencing of thermal source.
Exist various being used for lid reversibly to be locked in device on the bowl with air tight manner.
Specifically, known pressure-cooking appliance adopts:
-bowl, it comprises the bottom, from this bottom and the periphery in this bottom extended upward sidewall, this sidewall ends at from the edge that extend internally of sidewall towards bow interior extension; Go out to make can be near the opening of bow interior for described extend internally edge limited, and has the medial surface of the bow interior of facing location; With
Lid, it is designed to be inserted in the bowl below the medial surface at the described edge that extends internally, thereby then presses described medial surface with air tight manner, thereby cooperates to form the boiling container of sealing with described bowl.
In the art, this utensil since adopted with the lid that must at first be inserted into before the top that the extends internally sealing of bowl contact in the bowl, and can be called as " pressure cooker " with inner installation lid.
In addition, there are various pressure cooker technology with inner installation lid.
In these technology, known " manhole (manhole) " type pressure cooker adopts: at first being the bowl that its top that extends internally limits elliptical openings, secondly is the lid with complementary elliptical shape.
Complementary elliptical shape makes and lid can be inserted in the bowl fully, lid is aimed at the opening in the bowl once being positioned at the below, edge that extends internally, thereby made it press the described edge that extends internally with sealing means.
Certainly, the design of this " manhole " type utensil is unsuitable for using circular lid in itself.
But, exist to be suitable for adopting the inner pressure cooker that lid is installed of having of circular lid.This utensil is commonly called " pressure cooker with flexible cover ".This utensil is based on the principle of utilizing a kind of like this lid, and this lid can make it can close the deformation geometry structure of bowl with air tight manner from its static geometry that can insert bowl is become under the effect of bending stress.
Pressure cooker with flexible cover also is known, and it comprises: bowl, and it extends internally edge limitedly goes out circular bowl opening; And lid, it is formed by rolled-up circular metal plate.When being in its static structures, lid has " rolling " shape, and promptly curved shape can be inserted into it and is positioned at the below, edge that extends internally in bowl.When being in its distressed structure, lid is the plate-like of general planar, makes it can be continuously and lean against equably on the medial surface at the edge that extends internally, thereby forms airtight container.For this reason, the edge that extends internally of bowl with contact area that lid contacts in be provided with the ring packing packing ring.It at first is that secondly the lid motion control device is bolt that this known utensil that has flexible cover also is provided with, this motion control device comprises the bar that is mounted to around being fixed on the lid or pivoting with lid all-in-one-piece Y-piece, and this bolt is mounted to respect to the Y-piece freely-movable and is designed to leaning against on the outside of bowl above the edge that extends internally.Bar applies the cam of tractive force via the center to lid and leans against on the bolt, thereby can make the more close bolt of lid.
The operation of this known pressure cooker is as follows:
In its static structures, lid is inserted into is positioned at below, its edge that extends internally in the bowl, bolt leans against on the top side at the described edge that extends internally simultaneously.Then, user's described bar that pivots, thus the center of lid is applied power, thus make lid towards keeping static bolt motion.So lid leans against on the downside at the edge that extends internally of bowl and flexural deformation until reaching the deformation position that its periphery presses the edge that extends internally of bowl equably, thereby can form the Sealed steam cooking container.Then, the user is put into the Sealed steam cooking container that forms on the thermal source, thereby temperature and pressure in vogue in the container is raise, thus under the steam pressure effect food in the boiling container.
In addition, in order to prevent anyly in digestion process to open container out of turn,, thereby cause all catastrophic effects that may therefore cause because this opening can cause that lid penetrates suddenly, be well known that the utensil lid of prior art can be provided with opens safety device.This device is designed to when pressure in vogue in the container surpasses predetermined safety level described rod lock is in place.The described safety device of opening comprises the safety cock that is mounted to vertical slip on lid.As long as pressure in vogue in the container is smaller or equal to predeterminated level, this safety cock just remains on lower position under the effect of himself weight.In case pressure in vogue in the container surpasses predetermined safety level, safety cock raises and is inserted in the groove that is set directly in the bar.As long as safety cock is bonded in this groove, will applies the mechanical caging effect that prevents that bar pivot from changeing, thereby prevent that lid from opening.
Though this known utensil is satisfactory substantially, but there are some defectives.
Therefore; although the bowl of described known utensil is provided with a pair of handle that utensil can be held by its user that is exclusively used in; but described user can directly hold the utensil of closing by the control lever that is used to lid is moved usually intuitively, rather than uses and to aim at this and be arranged on handle on the bowl.This incorrect use of bar is especially owing to described bar when utensil forms boiling container occupies higher center on described utensil.Because described bar is necessary longlyer because of its major function (apply be enough to make the diastrophic tractive force of described lid to lid), the user is bigger as the temptation of handle with described bar.Bar is having problems aspect use, reliability or the physical security of utensil as this use meeting of handle.
When the user held utensil and mentions utensil by described bar, though lid is locked on the bowl, the weight of utensil can make bar open direction along lid and move.In other words, when the user only held cooking appliance by bar, the user can face the danger that lid unclamps from bowl suddenly, and it is unhappy that this bottom line also can make us, especially when bowl is equipped with the food for the treatment of boiling.
If utensil is lifted by described bar when it is under the pressure effect, promptly when safety cock was inserted in the groove that is arranged in the described bar, the lifting force that is applied on the described bar can produce the king-sized shearing force that affacts on the safety cock and pull power.
For example, if utensil is equipped with food and liquid, owing to, therefore be applied to power and the utensil weight basically identical that increases by leverage on the safety cock for of the pivot centralized positioning of safety cock insertion groove wherein away from described bar.Therefore, any danger for fear of safety cock fracture (this can cause the consequence of especially severe to the user) must make the material of making safety cock firm especially, utilizes big safety coefficient to carry out size design.The corresponding increase of cost that this oversize safety cock causes the prior art utensil.And, though with regard to related be inappreciable with regard to oversize, can not get rid of the danger of safety cock fracture at least in theory fully.
In addition, however, the big repeatability that is applied on the safety cock also can damage described safety cock, or makes safety cock worsen with respect to the adaptive degree of lid at least, thereby causes reliability (for example, sealing loss) and safety issue.
And the design of the known this utensil of prior art may have certain degree of difficulty for industrialization.
Owing to relate to relatively large manufacturing tolerance, especially for lid, therefore the groove in the described bar (this groove moves along circular stroke together with described bar) will be manufactured and be fixed on safety cock (its path is linear) on the lid consistent reliably is the comparison difficulty.
At last, indication that this known utensil does not provide is any (visual maybe can listen) makes the user can know when cooking appliance is locked really.Lack this locking indication and can cause the user to produce worry, because the user does not know whether utensil is correctly locked.

According to the present invention, utensil 1 comprises that at least one forms the bowl 2 of boiling container, and promptly described bowl 2 is designed to directly or receives food via the steaming tray (not shown) that is inserted in the bowl 2 and hold food.For example, and as shown in the figure, bowl 2 is about axis X-X ' circular symmetry.In the following description, adjective " axially " is meant the direction of described axis of symmetry X-X ', the vertical direction basically identical when this direction and utensil 1 normal running.Certainly, in the case without departing from the scope of the present invention, the shape of bowl 2 is not (but, for example be elliptical shape) of circular symmetry probably yet.
According to the present invention, pressure-cooking appliance 1 also comprises at least one lid 3, and it is designed to match to form boiling container with this bowl with bowl 2.
According to the present invention, cooking appliance 1 is for having the inner utensil that lid is installed.This means, in order to form the boiling container of sealing by bowl 2 and lid 3, at first need the below of inserting lid 3 in the bowl 2 fully and being positioned at its top free edge, described free edge limits that make can be near the opening of bowl 2 inside, described lid 3 is upwards moved both vertically, so that lid 3 is hermetically against the downside of described top free edge, thereby form the boiling container of closing with air tight manner.Have the structure of the inner pressure-cooking appliance that lid is installed and operation based on total principle itself be known.
By traditional approach, utilize such as the metal material of stainless steel or aluminium and make bowl 2, and this bowl has bottom 2A, this bottom is for example for plate-like and for example be provided with alternatively and synthesize assembly by the heat conduction of forge hot (hot beating) installation.As shown in the figure, bowl 2 has sidewall 2B, and it preferably has annular shape and extends upward from the periphery of bottom 2A.The edge 2C that extends internally extends internally from sidewall 2B.The described edge 2C that extends internally has the inboard that faces bowl 2,, faces the medial surface 20C of 2A location, bottom that is.Preferably, and as shown in the figure, sidewall 2B extends to top 21B from the bottom 20B that is connected to bottom 2A periphery, the edge 2C that this top extend past extends internally, and this edge that extends internally is towards the center of bowl 2, promptly towards axis X-X ' radial convergence.
Preferably, the edge 2C that extends internally comprises the section 21C that continues the general conical of extension from sidewall 2B, described tapered segment 21C ends at the edge 22C of volume, the edge that should go up volume is formed for receiving the groove of ring packing packing ring 4, and this packing ring is used to the medial surface 20C of the edge 2C that extends internally to serve as a contrast.The edge 2C that extends internally limits and makes and can not only can put into the food for the treatment of boiling by this opening near the opening of bowl 2 inside, also can insert lid 3.
According to the present invention, lid 3 is designed to be installed in the bowl 2 in the mode that can move between following position at least:
-closed position (shown in Fig. 3), in this position, described lid matches with bowl 2 to form boiling container, and this boiling container seals substantially, thus the promptly enough airtight pressure of this internal tank that can make raises; With
-open position (shown in Fig. 1 and Fig. 2), in this position, described lid can make the inside and the external communications of container, makes internal tank pressure in vogue be substantially equal to atmospheric pressure.
In other words, according to the present invention, lid 3 can be installed in the bowl 2, and promptly lid can be inserted in the bowl, and is in intended orientation, thereby this lid can move between its closed position and its open position in a controlled manner.
In the embodiment that illustrates in the drawings, when lid 3 is in its closed position, form the contact of basic sealing against the medial surface 20C of the edge 2C that extends internally by its end face 3A.On the contrary, when lid 3 was in its open position, it left the edge 2C that extends internally, and raise thereby prevent to occur in the container any pressure.Lid 3 is preferred mobile and from open position move towards the closed position (vice versa) by (be downward from the closed position when open position move perhaps) vertically upward.
For lid 3 is installed in the bowl 2, utensil 1 of the present invention advantageously also comprises the assembly 10 that is mechanically connected on the lid 3, and described assembly 10 is designed to place against the top of bowl 2.Lid 3 advantageously is mounted to respect to assembly 10 and moves between two final positions, when assembly 10 in fixing and static mode (as shown in fig. 1) when putting bowl edge 22C, described two final positions correspond respectively to open position and closed position.Under situation of the present invention, butted part on being connected to lid 3 (being formed by assembly 10 in this embodiment) is when keeping static in the mode against bowl 2, thereby think that lid 3 is installed on the bowl 2, so lid 3 pre-determined bit are positioned in bowl 2 below the edge 2C that extends internally, thereby described lid can move with respect to described butted part with respect to bowl.
In order to make following description simple, only with reference to having the inner pressure cooker that lid is installed, wherein the lid 3 of this pressure cooker is deformable, promptly can be by applying the shape that the mechanical stress that controlled by the user changes lid below.But the present invention is not limited to the inner pressure cooker that lid is installed of having of any particular type, and instruction of the present invention also can be applicable to inner pressure cooker, especially the manhole-type pressure cooker that lid is installed of having of other types fully.
In the embodiment that illustrates in the drawings, therefore lid 3 is deformable lid, it is suitable for conversion between static geometry (shown in Fig. 4) and deformation geometry structure (specifically illustrating) in Fig. 3, the medial surface 20C below that described static geometry can be inserted into described lid to be positioned at the edge 2C that extends internally in the bowl 2, and described deformation geometry structure makes the described lid can be against the medial surface 20C of the edge 2C that extends internally and form the contact of basic sealing, and this medial surface preferably is lined with seal washer 4.
In order to make the user can optionally open and close boiling container, lid 3 is preferably the lid of reversible deformation.This expression lid 3 is made by elastomeric material and is forced in the elastic range of described material and is out of shape.Preferably, lid 3 is a flexible cover, and promptly lid is designed to change shape under the effect of bending stress.For example, as itself was known in the prior art, lid 3 was made of the sheet metal of plate-like, rolled-up the making of this sheet metal is saddle under the inactive state of not being out of shape exterior mechanical stress, that is U-shaped curved shape (for example, at Fig. 1 and Fig. 4, see the same) roughly.In other words, under static state (do not have distortional stress), lid 3 advantageously has crooked disk shape, when when the top is seen corresponding to ellipse.By this warped shapes, described lid 3 can be inserted in the bowl 2 by the hole that is limited by the edge 2C that extends internally, and the diameter of the plate-like sheet (after bending) of formation lid 3 is greater than the opening diameter in the bowl 2.Having specifically illustrated lid 3 among Fig. 1 is inserted in and is positioned at the edge 2C below that extends internally in the bowl 2.
According to the present invention, pressure-cooking appliance 1 also comprises be used to lid motion control device 5 that lid 3 is moved between its closed position and its open position, and described control device 5 is mounted at least corresponding to the primary importance (specifically illustrating among Fig. 3) of lid in the closed position 3 with motion between corresponding to the second place (specifically illustrating among Fig. 1 and Fig. 2) of the lid 3 that is shown in an open position.
For example, in the embodiment that illustrates in the drawings, be used to make the control device 5 of lid 3 motions to be designed to apply along axis X-X ' power of approximate vertical, described power preferably is applied to the center of lid 3, thereby can make lid 3 carry out following motion:
-make lid 3 move to its closed position (shown in Fig. 3) by applying vertical distraction power upwards from its open position (shown in Fig. 1 and 2); With
-on the contrary, make lid 3 move to its open position (shown in Fig. 1 and Fig. 2) from its closed position (shown in Fig. 3) by removing the tractive force that is applied, described lid 3 turns back to its closed position under the effect of its deadweight.
As shown in the figure, when utensil is when having the pressure cooker of flexible cover, control device 5 plays two kinds of effects, that is, make the effect of lid 3 motions and make the effect of lid 3 distortion (bending), and these two kinds of effects are recurred.As will be described in more detail above, under the effect of the supercentral vertical distraction power that is applied to lid 3 by control device 5, lid 3 at first roughly along the vertical-path motion of the X-X ' that parallels to the axis up to its near its periphery till the edge 2C that extends internally, this edge that extends internally is lined with ring packing packing ring 4 on the 20C of side within it.When lid 3 during against the edge 2C that extends internally (via the seal washer 4 between the bottom surface 20C of end face that is plugged in lid 3 and the edge 2C that extends internally), the upwards tractive force continuation effect that applies by control device 5, thus make lid 3 with the bend mode strain.
This distortion makes lid 3 be the plate-like of general planar (no longer crooked), and this shape makes lid be complementary with the shape of the edge 2C that extends internally substantially evenly and continuously on its whole periphery.The boiling container of Xing Chenging enough seals like this, thus make food under greater than the pressure of atmospheric pressure by boiling.In other words, in the embodiment that illustrates in the drawings, be used to make the control device 5 of lid 3 motions not only to make lid 3 motions, be its deformation geometry structure but also described lid is become from its static geometry, vice versa.Therefore, by being used to make control device 5 conversion of realization of lid 3 motions from a kind of geometry to another kind of geometry.
Advantageously, be used for making the control device 5 of lid 3 motions to be combined in assembly 10.In the embodiment that illustrates in the drawings, utensil 1 also comprises the bolt 6 that is formed for the butted part that docks with bowl 2, and described bolt 6 is designed to against the lateral surface of the edge 2C that extends internally.Therefore, bolt 6 is designed to the aperture arrangement across bowl 2, thereby is resisted against the outside of the edge 2C that extends internally in two zones relative on diameter, and is concrete as shown in Fig. 1 to Fig. 3.Advantageously, bolt 6 is formed by the long and thin metal plate of longitudinal extension between two opposed ends, and each in these two ends is provided with corresponding sagging edge 6A, 6B, thereby can guarantee that bolt 6 correctly locatees and be centered on the bowl 2.Under situation of the present invention, when bolt 6 (or the device that ought anyly be equal to) leans against on the bowl 2 and is positioned at its top and against the top of bowl 2 (in the present embodiment simultaneously, form by the edge 2C that extends internally) time, think that lid 3 is installed in the bowl 2, for example shown in Fig. 1.
Advantageously, be used to make the control device 5 of lid 3 motions to comprise the moving lever 7 that is designed to by user's manual activation.
Advantageously, bar 7 is mounted to respect to bolt 6 at least corresponding to the primary importance (shown in Fig. 3 and Fig. 5) of the primary importance (closed position) of control device with motion between corresponding to the second place (Fig. 1 is shown in Fig. 2 and Fig. 4) of the second place (open position) of control device 5.Preferably, bar 7 is mounted to respect to bolt 6 and winds pivot axis Y-Y perpendicular to axis X-X ', pivots.Further preferably, bar 7 is connected to lid 3 via power delivery system 8 and preferably is connected to the center of described lid 3, thereby is pivoted to its primary importance and the center of lid 3 is applied tractive force upwards from its second place by bar 7, and vice versa.
Among the embodiment that illustrates in the drawings, power delivery system 8 comprises at least one connecting rod 8A, its first end pivots and is connected on the bar 7, with around paralleling to the axis Y-Y ' but with respect to the pivot axis of this axis bias, and second end of this connecting rod pivots and to be connected to U-shaped securing member 8B, this securing member for example by riveted and fixed on lid 3.
But the present invention is not limited to comprise the control device 5 of the pivot mounting rod 7 of the system that is used to activate connecting rod 8A.For example, control device 5 also can be arranged to not comprise bar, but comprises the control wheel that is connected on the gear that is used to activate the rack and wheel power delivery system.
Certainly, in the case without departing from the scope of the present invention, in embodiment as shown in FIG., equally play two kinds of effects, it is also contemplated that control device 5 only works to make lid 3 (in its whole motion) motion, for example in the embodiment corresponding to the manhole-type pressure cooker, wherein elliptical cover only presses the edge that extends internally with sealing means and therefore is not out of shape.
Also can imagine, in having the embodiment of deformable lid, control device 5 with the deformation pattern except that bending to lid 3 active forces.
According to the present invention, pressure-cooking appliance 1 also comprises the latch piece 15 that can start/discharge, this latch piece is designed to when being activated, prevent to be used to make the control device 5 of lid 3 motions to arrive its second place (opening) corresponding to lid 3 from its primary importance (closing) corresponding to lid 3, described latch piece 15 with container in the irrelevant mode of stress level in vogue start.In other words, latch piece 15 is designed to carry out the function of its mechanical caging control device 5, and the stress level that prevails in the airtight boiling container of not considering to form by bowl 2 and lid 3, promptly, even the inner pressure in vogue of bowl 2 are substantially equal to (or in fact less than) atmospheric pressure, control device 5 also can stop at its primary importance by latch piece 15.By this feature, because latch piece 15 is in case startup just can prevent any motion of described control device 5 towards its second place, thereby prevent any out of season the opening of lid 3, thus the user can be with control device 5 as the handle of mentioning utensil without any danger.Therefore, latch piece 15 has been realized the effect of positive lock control device 5.
Advantageously, latch piece 15 matches with control device 5, thereby starts automatically when described control device 5 arrives its primary importance.By this technical characterictic, latch piece 15 is self-startings, that is, the function association between described latch piece 15 and the control device 5 is: make that latch piece 15 is activated when control device 5 arrives its primary importance, thereby prevent that control device 5 from returning its second place.By this feature, utensil 1 uses especially simple and safety, this be because when close cap 3 latch piece 15 with container in stress level in vogue irrespectively start automatically, the user does not need oneself to start described latch piece.For this self-starting function is provided, be used to make the control device 5 of lid 3 motions to be advantageously provided cam 50, latch piece 15 self is provided with ratchet 150 simultaneously, this ratchet has with latch piece 15 and is in the corresponding elastic recovery structure of starting state, described cam 50 and described ratchet 150 mechanically match with interlocking when control device 5 arrives its primary importance, thereby prevent that control device 5 from returning its second place.
In the specific embodiment that illustrates in the drawings, cam 50 is integrally formed with bar 7, and the pivot axis Y-Y ' that therefore is mounted to distaff 7 pivots.Described cam 50 be designed to be arranged on ratchet 150 on sliding surface 150A slide against mode match, opposing is applied to the elastic-restoring force on the ratchet 150.More precisely, cam 50 has inclined surface 50A, and this surface design becomes when control device 5 motions to slide against the sliding surface 150A of latch piece 15.The bottom of sliding surface 150A is extended with and is the shoulder 150B that the slope changes and form abutting part.
Cam 50 itself also is provided with the shoulder 50B of complementary abutting part form, and this shoulder aligns with shoulder 150B by the ratchet 150 that returns elastically, thus by shoulder 150B and shoulder 50B mutually against making latch piece 15 and bar 7 interlockings.By these technical characterictics, when bar 7 during from its its primary importance of second place break-in, it back promotes latch piece 15 by complimentary surface 50A, the 150A elasticity that cooperatively interacts, and makes latch piece 15 return elastically and makes latch piece 15 and bar 7 interlockings by described shoulder 50B, 150B are alignd mutually up to the slope change corresponding to shoulder 50B, 150B.Therefore, even when the user holds the utensil 1 of closing by bar 7, also can prevent any out of season the opening of utensil.In other words, the embodiment shown in the figure is based on adopting claw as latch piece 15.Claw is back into continuously with latch piece is in the corresponding latch-up structure of its starting state, and can temporarily break away from this structure by acting on the cam 50 of bar 7 one, returns elastically the shoulder 50B interlocking with cam 50 then.Claw returns elastically it and returns with rest position and also produce the sound of closing that click rattles away, thereby informs that user's utensil 1 is correctly locked, thereby makes user's feel at ease (this if desired words of confirming again).
In the preferred implementation that illustrates in the drawings, latch piece 15 is installed into the effect of moving and continuing to bear back-moving spring 16 with respect to lid 3, and this back-moving spring promotion latch piece 15 turns back to latch piece 15 and is in the corresponding primary importance of starting state (specifically illustrating among Fig. 3).But under the situation that does not deviate from scope of the present invention, imagination latch piece 15 can be installed into and can not move with respect to lid, but only can strain to match with cam 50, this also is very feasible.
Advantageously, latch piece 15 is provided with manual control piece 15A, and this manual control piece makes the user can position action with release bar latch fitting 15, thereby allows bar 7 to return its second place from its primary importance.Manually control piece 15A preferably directly is made of the part of latch piece 15 self, and for example constitutes by the inclined plane of direct forming on ratchet 150.Advantageously, even be folded to following time at bar 7 in its primary importance (closed position) in order to make, the user also can be provided with the slit 17 that connects bar 7 directly manually near the described inclined plane that forms control piece 15A.So the user can be by applying the restoring force that horizontal pressure force is applied by spring 16 with opposing to ratchet 150, thereby and discharge shoulder 50B from ratchet 1 50 and make the bar 7 can freely-movables.
In particularly advantageous mode, manually control piece 15A itself can start/discharge, and described manual control piece 15A makes that when being activated the user can release bar latch fitting 15.On the contrary, when manual control piece 15A was released, the user can not remove the interlocking between latch piece 15 and the bar 7.
Preferably, be used to make the control device 5 of lid 3 motions to be installed into motion between its primary importance (shown in Fig. 3 and Fig. 5) and the 3rd position (shown in Fig. 6), control device 5 is identical to its primary importance (Fig. 3 is with shown in Fig. 5) travel direction from its second place (for example, shown in Fig. 1) to its 3rd position travel direction and described control device 5 from its primary importance.In other words, the primary importance of control device 5 is in the centre position that constitutes on the stroke of control device 5 between the second place and the 3rd position.This is also illustrated in from its 3rd position when its second place (vice versa) conversion, and control device 5 must be through its primary importance.Preferably, primary importance is for replying the position, so control device 5 is when being in its 3rd position, nature can be tending towards returning its primary importance carry out against.This returns effect advantageously by following realization: therefore when control device 5 (and bar 7) when being in its 3rd position, connecting rod 8A is positioned to respect to the vertical axis X-X through the pivot center of bar 7 angledly ' tilt slightly.This angle offset combines with the elastic reactance that lid 3 applies, and causes control device 5 to be continued to promote to return its primary importance.
Advantageously, control device 5 matches with the manual control piece 15A of latch piece 15, thereby described control piece 15A at first is released when control piece 5 is in its primary importance, secondly is activated when control device 5 is in its 3rd position.In other words, when control device 5 was in its primary importance, because manually control piece 15A is released itself, the user can not release bar latch fitting 15.On the contrary, when control device 5 was in its 3rd position, manually control piece 15A was activated, thereby allowed user's release bar latch fitting 15, thereby release lever 7 makes it movable.Preferably, bar 7 remains on freely-movable between the 3rd position and the primary importance.
These technical characterictics make can obtain especially favourable additional security function.If the user holds utensil 1 by control device 5 (in this embodiment, by bar 7), then described control device is tending towards moving to its second place (opening corresponding to lid 3) under the weight effect of utensil 1 naturally.When control device 5 arrives its primary importances, stoped by latch piece 15 towards this motion of the second place, this motion is freely between the 3rd position and primary importance.In other words, when the user holds by bar 7 and mentions pressure cooker 1, described bar must its primary importance (shown in Fig. 3) enter against.
In this primary importance, latch piece 15 is discharged.Therefore, if the user wants release cooking appliance 1, described user must at first place it on the stable supporting surface, so that manually make control device 5 enter its 3rd position (shown in Fig. 6) from its primary importance, latch piece 15 is discharged.
The same as specifically seeing among Fig. 3, Fig. 6 and Fig. 7, in order to realize startup/release function of manual control piece 15A, it is contemplated that to each shoulder 50A, 150B the corresponding tooth 51B of portion, 151B all are set, the described tooth 51B of portion, 151B match by being hooked in together, move when bar 7 self is in its primary importance (shown in Fig. 3) to prevent latch piece 15.On the contrary, when bar 7 from its primary importance when pivoting with corresponding the 3rd position, the 3rd position (shown in Fig. 6) (preferably very near primary importance) of control device 5, the 51B of tooth portion, 151B break away from, thereby allow the stroke of user's actuated latch part 15 (by press surface 15A) with release lever 7.
Advantageously, utensil 1 of the present invention comprises that also described safety cock is different with latch piece 15 to pressure-sensitive safety cock 12 in vogue in the container.Safety cock 12 is mounted to respect to lid 3 and moves between the primary importance and the second place, when the stress level in the container is lower than the predetermined safety level that is complementary with user's security, described safety cock is in primary importance, and when the stress level in the container met or exceeded described predeterminated level, described safety cock arrived the second place.
In other words, safety cock 12 is designed to move under the driving force effect that pressure was applied in vogue in the container that is formed by bowl 2 that is bonded together with sealing means and lid 3.
Advantageously, latch piece 15 matches with safety cock 12, make when described safety cock 12 is in its second place (corresponding to the stress level in the bowl more than or equal to predetermined safety level), safety cock is locked in its starting state with latch piece 15, and irrelevant with the state (starting or release) of manual control piece 15A.By this technical characterictic, when pressure in vogue in the boiling container during greater than predetermined safety level, can not release bar latch fitting 15, thus anti-stopping bar 7 moves to its second place (opening corresponding to lid) from its primary importance (cutting out corresponding to lid 3).In other words, safety cock 12 forms opens safety device, and this device makes to be opened cooking appliance when the pressure that can avoid the user to prevail is enough high and cause danger in cooking appliance 1, and for example lid is penetrated suddenly and boiling hot food sputter.
Preferred and itself be well known that safety cock 12 matches with the hole 13 that connects lid 3 settings, thus described hole 13 is closed when safety cock 12 is in its second place, and when safety cock 12 is in its primary importance, do not stopped.Like this, when safety cock 12 arrives its second place, pressure in the boiling container can raise, and when safety cock 12 is in its primary importance, because hole 13 makes the inside of container fully be communicated with outside, pressure in the boiling container can not raise, thereby prevents that pressure from increasing to above predetermined safety level.
Advantageously, latch piece 15 matches with safety cock 12, thereby prevents that when latch piece 15 is released safety cock 12 from arriving its second place from its primary importance.Like this, safety cock 12 also provides incorrect closed safe function therefore except providing it to open the security function.
As mentioned above, as long as latch piece 15 is not activated to prevent any uncap out of turn 3, safety cock 12 just can not arrive its second place, as long as safety cock 12 does not arrive its second place, the pressure in the boiling container just can not be elevated to above level of security.
In order to prevent that latch piece 15 is in its starting state when control device 5 leaves its primary importance or cuts out corresponding its 3rd position with lid 3, described latch piece 15 matches with the control device 5 that is used to lid 3 is moved, make that latch piece 15 just remains in its release conditions as long as control device 5 does not arrive its primary importance (shown in Fig. 3) from its second place (shown in Fig. 1).This technical functionality for example can obtain by cam 50 suitably is shaped, cam design is become as long as bar 7 is not in its primary importance, just continue to keep making ratchet 150 (itself is leaning against on the cam 50 under the effect of the power that spring 16 applies always) leave its elastic recovery position, promptly leave its enable position.
In the preferred implementation that illustrates in the drawings, safety cock 12 cooperates with bar 7 indirectly by latch piece 15.Made and to guarantee that also utensil 1 is locked under the situation that in described utensil, does not have pressure even should indirectly cooperate.
Design also makes and the design that can optimize safety cock 12 makes the design of safety cock not depend on safety cock 12 and bar 7 direct interactions like that in the prior art for another example indirectly.
Preferably, as shown in FIG., latch piece 15 is provided with safety piece 18 (more specifically seeing) in Fig. 8 and Fig. 9.
Described safety piece 18 is provided with slit 18A and dividing plate 18B, and described safety piece 18 is arranged in the path on safety cock 12 motion institute edges, thereby when latch piece 15 is in its elastic recovery position, slit 18A is in and safety cock 12 vertical alignments, thereby allow the freely-movable in slit of described safety cock, and when latch piece 15 left its answer position, dividing plate 18B was in and safety cock 12 vertical alignments, thereby stopped that safety cock 12 moves towards its second place from its primary importance.
More precisely, latch piece 15 is formed by the element of single-piece one, for example make by moulding of plastics materials, and this latch piece by at first be form ratchet 150 and manually the two claw of control piece 15A secondly be that safety piece 18 constitutes.This independently a body member be installed into the motion of the mode (perpendicular to axis X-X ') that moves horizontally with respect to bolt 6, and continuing to bear the restoring force of spring 16, this restoring force is used to push a described body member so that it enters and the corresponding rest position of the starting state of latch piece 15.In this starting state, slit 18A aligns with hole 13, and described slit 18A also has enough big diameter so that safety cock 12 can be in this slit freely-movable up to arriving its second place with sealing means blind hole 13.In this second place, because the diameter of slit and the diameter of safety cock 12 adapt, so latch piece 15 can not carry out any translational motion.
This guarantees that lid 3 can be by unexpected release when keeping the dangerous pressure level in the container.
On the contrary, reply and during rest position, slit 18A no longer overlaps with hole 13, thereby prevent safety cock 12 its second place of arrival that moves upward when latch piece 15 leaves it.Therefore, safety cock 12 can not blind hole 13, thereby prevents that the pressure in the utensil 1 from increasing.Dividing plate 18B can be made of continuous plate of material.But as shown in FIG., it is contemplated that dividing plate 18B is provided with notch 180B, the top 12A that this notch is used to receive safety cock 12 is with to its channeling conduct and/or allow the user see, should understand the section 12B that described safety cock 12 has major part, this section can not be received among the notch 180B and therefore center on notch 180B against safety piece 18.The feasible size that can very suitably limit safety cock 12 of this design, so that described safety cock bears the bar 7 direct acting power of pullling of installing by pivoting can be in prior art, but only relative motion in the translational motion of safety piece 18, this safety cock only bears the restoring force that spring 16 applies in horizontal plane.
Advantageously, be used to make the second place of control device 5 of lid 3 motions for replying the position.Though obtain in the embodiment that this technical characterictic does not illustrate in the drawings embodying, but certainly also within the scope of the invention, this technical characterictic can be guaranteed when latch piece 15 non-locking bars 7, pressure cooker 1 can not produce pressure (can turn back to its open position because of bar 7 thereby with nature, prevent that utensil from producing pressure).
" spring " effect that can be by lid itself with arrange that suitably power delivery system 8 combines, control device 5 returns its second place that this returns effect and realize being used in the pressure cooker with deformable lid making.
(not shown) it is also contemplated that in another embodiment: first (or 3rd) position of control device 5 that is used to make lid 3 motions is also for replying the position.Also can obtain this technological means, thereby can be convenient to close and latch piece 15 is operated to open by suitably arranging power delivery system 8.
Cooking appliance 1 following operation shown in the figure.
In this stage, cooking appliance 1 is in structure illustrated in figures 1 and 2, the user pivots counterclockwise through certain angle stroke (limiting with respect to Fig. 2, Fig. 3 and Fig. 6) bar 7 then, the trip is corresponding to semicircle roughly, is about 165 ° of angles corresponding to the primary importance (closed position) from the second place (open position) of bar to bar for example.
Its effect is to be delivered to the center of lid 3 via the connecting rod 8A tractive force that will make progress, and this moment, bolt 6 continued to lean against on the edge of bowl 2.In the phase I, the effect of this tractive force is that lid 3 is moved upward, and makes lid flexural deformation during against the set packing ring 4 of the edge 2C that extends internally when lid then.Simultaneously, cam 50 pushes away its elastic recovery position with ratchet 150, thereby when bar 7 arrives its primary importance, makes ratchet finally can turn back to it and reply the position.So, cam 50 and ratchet 150 interlockings, pressure-cooking appliance 1 is in the structure shown in Fig. 3.In this structure, safety cock 12 freely-movables are by slit 18A, and therefore can arrive its second place, safety cock in its second place with air tight manner blind hole 13 and with latch piece 15 locks in place.When digester cycle finishes, in case make the internal tank atmospheric pressure that descends back by any known mode, the user will initiatively make utensil 1 release by bar 7 being applied downward slightly pressure, thereby makes described bar enter its 3rd position, and this position is preferably rest position.Its effect is that the 51B of tooth portion, 151B are broken away from mutually, makes the user to make its release by directly and flatly pushing via surperficial 15A on latch piece 15.This makes bar 7 discharge from latch piece 15, thereby the user can make bar 7 move through certain angle stroke (limiting with respect to Fig. 2, Fig. 3 and Fig. 6) clockwise, thereby make bar enter its second place (open position, this position is preferably rest position) from its primary importance (closed position).The effect that bar 7 moves on this clockwise stroke is that lid 3 is moved downward, and bending force is reduced.So lid 3 is got back to its original shape that is not subjected to the mechanical stress effect, the crooked character (specifically seeing in Fig. 4) of described original shape can easily be taken out it from bowl 2.
